Find LCM of 684,513,665,763 with Prime Factorization
3 | 684, 513, 665, 763 |
3 | 228, 171, 665, 763 |
7 | 76, 57, 665, 763 |
19 | 76, 57, 95, 109 |
4, 3, 5, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 19 x 4 x 3 x 5 x 109 = 7828380
Therefore, the lowest common multiple of 684,513,665,763 is 7828380.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
684 x 513 x 665 x 763 = 178040846340
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
513 : 1, 3, 9, 19, 27, 57, 171, 513
665 : 1, 5, 7, 19, 35, 95, 133, 665
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,513,665,763, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
513:3x 3x 3x 19
665:5x 7x 19
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 19x 19 = 22743
Therefore, the value for common factors is 22743.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 178040846340/(1x22743)
LCM = 178040846340/22743
LCM = 7828380
Thus, we can understand that the LCM of 684,513,665,763 is 7828380.
